I once visited a team that had fifteen layers in their code. That is: If you wanted to display some data in the database in a web page, that data passed through 15 classes in the application. What did these layers do? Oh, nothing much. They just copied data from one object to the next. Or sometimes the “access object layer” would perform a check that objects were valid. Or perhaps the check would be done in the “boundary object layer”. It varied,...
